DataTable - Lazy DataTable has built-in support to deal with huge datasets. In order to enable lazy loading, a LazyDataModel needs to be implemented to query the datasource when pagination, sorting, filtering or live scrolling happens. This example uses an in-memory list to mimic a real datasource like a database.

In a real application, loading should be executed with the query built using the information passed to the load method.
